RS321BKXF

Jiangsu RUNIC Tech · Operational Amplifier · SOT-23-5

RS321BKXF from Jiangsu RUNIC Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 +IN input Positive (noninverting) input; the common-mode input range is -0.1V to +5.6V with Vs = 5.5V.
2 V- power_in Negative (lowest) power supply; single-supply operation is 2.5V to 5.5V, or dual-supply ±1.25V to ±2.75V.
3 -IN input Negative (inverting) input; the same common-mode input range of -0.1V to +5.6V applies with Vs = 5.5V.
4 OUT output Output; rail-to-rail output with 120 mA typical source current at 25°C, and continuous short-circuit to ground is permitted for one amplifier per package.
5 V+ power_in Positive (highest) power supply; absolute maximum supply voltage (V+) - (V-) is 7V.
